Item Description

It isn't just about flexibility; it's about bending the note till it rings true. 

Martin SP Flexible Core strings have a thin but strong core wire and a thicker wrap wire which allows them to be flexible and easy on the fingers while holding standard tension. SP Flexible Core strings feel soft to the touch, making them ideal for beginners. But don't be fooled by comfort! Just ask Tommy Emmanuel who performs with Martin's SP Flexible Core strings night after night. With SP Flexible Core, you get total flexibility and total control.

Martin & Co. designs and manufactures the strings themselves. Like their guitars, each string is made with patience, care, and precision with only the highest quality materials producing strings with exacting tone and superior performance. Not only are their packaging materials minimized and 100% recyclable, but the envelopes reduce the tarnishing effect on the strings.

Great for the finger players
Was using silk cored 80/20 for a while, after moving from phosphor bronze, these give the best of both worlds and don't break the bank like the other ones I was using prior

Why aren't they made in the USA?
I bought these for my young granddaughter to learn to play on, they seemed ideal for that, and they sound pretty good on her 000 size old Guyatone. Easy to cord and easy on her fingers too. They do seem to not last as long as I'd like, they go flat too soon. Hey Martin; Why aren't these being made in the USA, why move your string production to Mexico? I'll not buy anymore.
ProsGreat for beginners. Easy to cord. Easy on fingers.
ConsDon't last as long as I'd like for them to. Made in Mexico, not the USA.

The difference is astounding
I had the good old Elixirs on my Furch OM-33 as that's what it came with and I used a few sets.

I thought I'd give these a go and the tone and sustain was totally night and day.

Thick, deep bass notes, sweet clarity in the mids and treble tones, resonance. Just superb.

Am completely sold on these. Just bought 10 more sets.
ProsTonal improvement and sustain.
ConsNothing yet.

Good strings for practicing and recording
I have played several sets of Martin flexible core (silk and steel). These strings deliver a soft, balanced tone and are really flexible and don't require much strnght in your hands, so they're ideal if you have to practice for a long time. Unfortunately, their duration is short.
ProsNice tone, soft strings
ConsThey tend to loose their brilliancy and crispness in a few hours.

Great for Martin Backpacker
The small scale and body of a Martin Backpacker travel guitar prsent challenges in terms of sound and playability. These silk and phosphors are a great fit for the Backpacker.
ProsBalanced sound that projects well. Easy on the fingers.

great for my vintage 00!
These have a soft and warm sound that really suits my mahogany topped, maple backed (yes, that's a weird wood combo) 70's Harmony 00 frankenstein guitar. I was a bit worried that the low E would be too floppy, but that's not the case. Great price, too! Lovely for finger style!

Really Comfortble playing
I purchased assortment sets from different brands and types looking for easiest playing fact.
I am a beginner player for a couple of years ago and I am tired of suffering frustation with several "lights" strings which really do not hurt my fingers and make buzzing if low action is adjusted, then they miss tone. richness and going dead. Even I purchased one 11-52 set of Martin FX Flexible Core Phosphor Bronze and tried previously than these silk FX130.
Nothing to do with..., I retired the first ones in a couple of weeks and when FX130 were installed, my BREEDLOVE came to life and my fingers too!!!!
No buzzing (my guitar is adjusted at low action) and good enough rich sound.
I tried many others brands, always lights, even with silk, and these are the best ones. In the others always I was facing buzzings or sound richness missing if so...
Until my fingers can stand others, I think my two years search is finished.
ProsPlayability, comfortability Good Price Sound richness good enough and sustain
ConsNothing by the momento maybe MARTIN could try to manufacture higher gauge if main playability specs are maintained.

Silk and Phosphor are incredible.
I got two sets and I've gone back and ordered 6 sets again. That will make 14 sets in all. I restrung 3 of my guitars with them. My Martin D-35 sounds so sweet with these strings on there. It's still a sonic cannon, but now it has a more balanced tone. The bass "E" sounds like a piano. It just rings. Mike, keep selling these strings and I'll keep buyin' 'em.
ProsThey make it so easy to play my guitars for hours. They don't hurt at all. My guitars all sound better. Perfect for solo performers.

Great Alternative to Silk & Steel
I use these on an acoustic Parker P8E.
ProsI love these strings not only for the beautiful, big sound I get (amplified, too!) but also because they don't require a higher action the way regular silk & steels do. Like nylon strings, plain silk & steels seem to vibrate in a huge arc, so action has to go higher to avoid fret buzz. The Silk & Phosphor strings give me the soft feel and big sound of silk and steel, but without such a big arc of vibration. I keep my action set the same for these as I do for steel strings. No buzz, easy play, beautiful tone. And they even look nice - see pics.
ConsI don't dislike anything about these strings. Maybe it'd be nice if Martin could coat them for longer life?

best all around string
I've been teaching guitar to children, teenagers and adults for over ten years. I find the Martin FX130 to be the best strings for beginners especially kids since their fingers are short and weak. The string's great flexability makes learning less frustrating for beginners and they can achieve success in less time. They have a nice warm sound and you can't beat the price. Only Martin would think of such a great product.
ProsTone Price Feel and touch
ConsCould break if strummed hard

Martin FX130 Silk and Phosphorous
I love these strings! I use them for all of my guitars because they bring out the best in them. I especially like the way my Masterbilt EF500RAS and my Breedlove come to life and sound so high end! Best strings I've ever used!

Martin FX130 Silk & Phosphor
I play rhythm at chuch. These FX130 strings are warm with lots of sustain. They seem to be holding up to my strumming better than "normal" phosphor bronze strings, possibly due to the flexible core. They also sound great fingerstyle. I like them so much I just ordered another batch from Strings and Beyond. Great strings at a great price!

Martin FX Silk and Phosphor Strings
Martin FX Silk and Phosphor Strings are true to the manufacturer’s description: (i) a sweet and melodic (ii) with remarkable playability at any fret position (iii) increased durability (iv) stay in tune and play longer (v) reduces finger fatigue and (vi) permits quicker transitions from string to string.
In my case, the transition is from Nylon to Steel and I am exceedingly pleased with how comfortably these strings allow me to shift from classical/flamenco guitar to finger-picking on my new Huss & Dalton 00 SP

Silk and Steel FX130
I put these on a hog 00 and they really sound terrific. The balance and warmness make these strings really great and the 80/20 phosphor bronze lights that they replaced really didn't make the guitar sound near as nice as this. I had heard these silk and steels were great strings on smaller bodies guitars and I would recommend anyone trying them. Nice clean sustain.
